Usage notes

The usage in sense 9 above, “to worsen a situation” is widespread but not wholly accepted. The original meaning of the word (see senses 4, 5 and 6 above) implies resolution of a problem, not worsening. It has been suggested (Fraser 1973) that the reverse usage arose by confusion with phrases such as compound interest.
